About Milton Coste

Milton Coste New York Real Estate Agent Headshot

Agent Details

Meet Milton

Milton Coste is a Licensed Associate Real Estate Broker at Keller Williams NYC with over 25 years of experience and more than 2,000 transactions closed throughout his career.

Born and raised in the Inwood and Washington Heights sections of Upper Manhattan, Milton's journey into real estate began unexpectedly. Working as an assistant at a nonprofit organization, he found himself surrounded by board members who were some of New York's top real estate developers and executives. Intrigued by the business, he launched his real estate career in the fall of 2001—and never looked back.

At his former company, Milton quickly rose to Managing Partner and Principal Broker by excelling in technology, marketing, leadership, skillful negotiation, and exceptional customer service. His track record spans residential, commercial, investment properties, sales, and leasing across all five boroughs. In June 2016, he joined Keller Williams NYC to continue serving clients at the highest level.

A lifelong learner and early adopter, Milton leverages cutting-edge technology, AI-powered tools, and automation to deliver a modern real estate experience. From AI-generated property marketing and automated lead nurturing to data-driven market analysis and predictive pricing models, he combines decades of street-level expertise with innovative solutions to give clients a competitive edge in any market. Custom-built property websites, virtual staging, 3D tours, drone photography, and AI-powered social media marketing are all part of his toolkit. Always learning, always evolving—because the best agents never stop growing.

As a lifelong New Yorker, Milton's extensive knowledge of market trends and the city's rich history sets him apart as your consultant of choice. Fluent in English and Spanish, he serves a diverse clientele of first-time buyers, seasoned investors, sellers, landlords, and renters. He is a proud member of REBNY, NAR, and HGAR.

Beyond real estate, Milton is a proud 2x girl dad—his greatest motivation and the reason he works hard to help families find their perfect home. When he's not closing deals, you'll find him cheering for the home team, exploring the cultural arts, or traveling and discovering new corners of the world.
